Official records classify it tentatively as a designed landscape feature, which is itself a phrase that admits uncertainty. What is known is that a roughly circular pit, measuring approximately 33 metres north to south and 25 metres east to west, sits on this rise, its outline clipped on one side by a field boundary running northeast to southwest. By the time anyone looked closely at it in September 1983, only slight traces of that outline remained visible on the ground.

The early Ordnance Survey mapping offers the clearest window into what this place once was. The 1838 edition of the six-inch OS map, one of the most detailed surveys of the Irish landscape ever undertaken, records the spot as an unenclosed coniferous tree plantation. A century later, the 1947 revision tells a different story: the trees are gone, and in their place the circular depression is depicted. Whether the pit predates the plantation, was created as part of it, or emerged only after the trees were cleared is not something the surviving evidence can settle. The plantation itself, being unenclosed, would have had no surrounding wall or bank, just trees growing on open ground, perhaps arranged deliberately as an ornamental feature on a country estate. That is the working hypothesis, at least. Archaeologists have looked at the site and concluded that the evidence does not support treating it as an ancient monument, though they have not ruled out the possibility either.
